Shehu Sani, the President of Civil Rights Congress based in Kaduna, said two explosions took place at the Assemblies of God’s Church near the centre of the city with a large Christian population and known as a major cultural and economic centre in Nigeria’s north.

“There were two explosions and the casualty figure may go up because some injuries were really critical,” he said on phone.

Another resident of the city, Miss Blessing Audu said that the explosion has caused panic among Christians celebrating Easter.

She said some parts of the church were damaged even as the vibration caused by the explosives were heard in several parts of the city.

An emergency worker on condition of anonymity explained that the bombs were planted in two cars near the church.

At least 50 people were killed amid fears that the casualties may rise from the blasts.

But who could have done this?

No one has yet claimed responsibility for the bombings, but the BBC reported that Boko Haram recently said it would carry out attacks in the area over the Easter holiday.

The radical group has carried out a series of attacks on churches and other locations on Christmas Day, including outside the church in capital Abuja, where 44 people died.

It is waging a bloody war against the government to seek the enforcement of strict Shariah law and the release of all its detained members.
